Product Description:

The HVR02.2-W025N/S201 is a power supply module produced by Bosch Rexroth Indramat for the HVR Power Supply Units series. As a regulated DC link supply, the unit converts three-phase mains power into a stable dc bus that feeds multiple Indramat drive controllers within an automation cell. By consolidating the energy conversion in a single cabinet component, it simplifies wiring, supports common braking and regeneration functions, and maintains the required system voltage for synchronous and induction servo axes.

The supply is manufactured by Bosch Rexroth Indramat, and it belongs to the HVR Power Supply Units series; within that family the hardware is identified as Design Version 2, meaning the control logic and protective circuits match the second mechanical revision. To produce the dc link, the input side accepts 3 x AC 380 V to 480 V (±10%) from the plant distribution network, so the device tolerates typical industrial voltage swings without derating. Thermal management relies on internal air with built-in blower, allowing the cabinet to remain closed while the integrated fan moves air across the heat sinks, keeping semiconductor junctions within rated temperatures during continuous loading.

Delivering 25 kW of apparent power, the unit can energize several axis drives simultaneously while still providing headroom for braking energy to be returned to the common rail. The resulting output is a regulated DC bus voltage, so downstream inverters see a constant link potential even when the supply network fluctuates or when multiple motors accelerate at once. Classified as an HVR Power Supply Unit, it interfaces directly with Indramat drive racks that share the same back-plane connectors. The internal control board also carries parameter coding that identifies the device as Series 02, streamlining spare-part selection and ensuring firmware compatibility with second-generation servo amplifiers.
